基于FPGA的光纤光栅解调系统的研究

 波长信号的解调是实现光纤光栅传感网络的关键，基于现有的光纤光栅传感器解调方法，提出一种基于FPGA的双匹配光纤光栅解调方法，此系统是一种高速率、高精度、低成本的解调系统，并且通过引入双匹配光栅有效地克服了双值问题同时扩大了检测范围。分析了光纤光栅的测温原理并给出了该方案软硬件设计，综合考虑系统的解调精度和FPGA的处理速度给出了基于拉格朗日的曲线拟合算法。 Abstract:  Sensor is one of the most important application of the fiber grating. Wavelength signal demodulating is the key techniques to carry out fiber grating sensing network， based on several existing methods of fiber grating sensor demodulation inadequate， a two-match fiber grating demodulation method was presented. This system is a high-speed， high precision， low-cost demodulation system. And by introducing a two-match grating effectively overcomes the problem of double value while expands the scope of testing. This paper analyzes the principle of fiber Bragg grating temperature and gives the software and hardware design of the program. Considering the system of demodulation accuracy and processing speed of FPGA，this paper gives the curve fitting algorithm based on Lagrange.

xilinx FPGAs在工业中的应用

　　The revolution of automation on factory floors is a key driver for the seemingly insatiable demand for higher productivity， lower total cost of ownership，and high safety. As a result， industrial applications drive an insatiable demand of higher data bandwidth and higher system-level performance. 　　This white paper describes the trends and challenges seen by designers and how FPGAs enable solutions to meet their stringent design goals.

智能照明控制器测量环境光线

Abstract: This application note explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The system presented in this document can be used to control all luminaires that are mains-supply operated.Controller software is also provided in hex format.
